Ether 12:12

For if there be no faith among the children of men God can do no miracle among them; wherefore, he showed not himself until after their faith.

The God of heaven, who has all power, who ignites stars and brings worlds into existence by speaking a word, who measures the heavens with the span of his hand and weighs the mountains in a balance, who sits on the horizon of the earth and views the children of men as grasshoppers, can do nothing if we do not let him. Our agency is sacred, and faith is a product of agency. If we do not see miracles in our lives, it is not because God lacks the power to perform them. We must looked inward, not outward, for the source of our lack.

Mormon 9:21

Behold, I say unto you that whoso believeth in Christ, doubting nothing, whatsoever he shall ask the Father in the name of Christ it shall be granted him; and this promise is unto all, even unto the ends of the earth.

If we want power from God, we begin with belief in Christ, as evidenced by our submitting to the first principles and ordinances of his gospel, which are faith and repentance, followed by baptism and the conferring of the Holy Ghost by one holding the proper authority.

We must trust with our whole heart and soul in Christ. He holds our very salvation and eternal life in his hands. When we trust him, we do not try to wrestle our salvation away from him as if we can save ourselves. No, we do not doubt in the least that he can and will redeem us.

With that trust and faith in Christ, we go to the Father in his name and ask for the help we need to strengthen and increase our faith. We ask him to change our hearts and minds from the squalor of the natural man to the humility of a disciple of Christ. Such a prayer will God always, always answer.

And his answer will be a miracle, for it is only by the miracle of the Christ's Atonement that a sinner can be washed clean and spotless.

God excludes no one from the promise of hope in this formula, to the ends of the earth and the end of time. Everyone can receive his grace. If we do not, it is only because we exclude ourselves by trying to get it some other way than how God has prescribed. He has the right to set the conditions by which we come to him. We have the choice to accept or reject those conditions. We do not, however, have the right to override the consequences of our choices.

Mormon 9:19-20

And if there were miracles wrought then, why has God ceased to be a God of miracles and yet be an unchangeable Being? And behold, I say unto you he changeth not; if so he would cease to be God; and he ceaseth not to be God, and is a God of miracles. And the reason why he ceaseth to do miracles among the children of men is because that they dwindle in unbelief, and depart from the right way, and know not the God in whom they should trust.

Moroni's indictment of our generation is unassailable. If miracles appear to have ceased among us, it us not because God has lost his power or changed his modus operandi. It can only be because we don't believe him anymore. If a person of true faith lives on the earth, God will work miracles in and through that person's life.

To be clear, faith is not restricted to Latter-day Saints, nor does every Latter-day Saint possess faith. The full power and authority of the holy priesthood resides in the Restored Church, but God works in every life to which he is invited and sought after. No one group of people has a lock on God's love.

Despite that fact, few people today believe in miracles. They believe in science, which they can touch, and attribute the rest to coincidence, luck, or the average of large numbers. They may as well live in the dark ages, where every phenomenon was attributed to witchcraft, the devil, or the alignment of the stars and planets. 
 
The antidote for living in the world without God is to choose faith and seek after him in trust. God truly has given us many scientific and technological miracles (which we, by the way, ascribe to our own brilliance and still ignore God's hand in the discoveries of laws of which he has always been the Master). These blessings he has given us out of love in spite of our weakness because he doesn't want to see us wallow in darkness. Yet he has so much more to offer! And so God waits for a glimmer of faith among us. If we can muster even the tiniest hope or a mustard seed of faith, God will nourish it and cultivate it and help it spring up unto a tree that bears fruit. And that fruit will be miraculous.

Mormon 9:11

But behold, I will show unto you a God of miracles, even the God of Abraham, and the God of Isaac, and the God of Jacob; and it is that same God who created the heavens and the earth, and all things that in them are.

The greatest miracle of God is Christ's Atonement and the plan of salvation. God must be a God of miracles to pull off our salvation. If we don't think God does miracles, then we don't think he can save us. And if that were the case, what good is he, and what good is life itself?

Mormon 8:26

And no one need say they [the Book of Mormon] shall not come, for they surely shall, for the Lord hath spoken it; for out of the earth shall they come, by the hand of the Lord, and none can stay it; and it shall come in a day when it shall be said that miracles are done away; and it shall come even as if one should speak from the dead.

The Book of Mormon refutes the claim that miracles do not happen in our day. Those who refuse miracles will refuse the Book of Mormon because the only way that book could come into existence is by the miraculous power of God. Do not say miracles have ceased until you have tested the Book of Mormon.

3 Nephi 29:6

Yea, wo unto him that shall deny the revelations of the Lord, and that shall say the Lord no longer worketh by revelation, or by prophecy, or by gifts, or by tongues, or by healings, or by the power of the Holy Ghost!

God is the same yesterday, today, and forever. What he has done in the past we will do among us today and in the future. God does not change, but men change. If he does no miracles among a people, it is not because he lacks the power, but because they lack the faith.

Helaman 16:20

But behold, we know that this is a wicked tradition, which has been handed down unto us by our fathers, to cause us that we should believe in some great and marvelous thing which should come to pass, but not among us, but in a land which is far distant, a land which we know not; therefore they can keep us in ignorance, for we cannot witness with our own eyes that they are true.

Physical proof is always demanded by those who refuse faith. The thing is, when they get the proof they demand, they do not accept it. Signs, wonders, and miracles are happening all around these people, and they dismiss the prophecies as lucky guesses. This is a lesson for us to learn about the Book of Mormon. Many people claim they would believe the Book of Mormon if they could only see the gold plates. But the reality is that they would only try to prove that the plates are a fraud. We first choose to believe, and then we are strengthened by evidence. Evidence never produces faith. It may catch our attention, but sooner or later we must make a conscious choice regardless of the evidence.

Helaman 16:6

But the more part of them did not believe in the words of Samuel; therefore when they saw that they could not hit him with their stones and their arrows, they cried unto their captains, saying: Take this fellow and bind him, for behold he hath a devil; and because of the power of the devil which is in him we cannot hit him with our stones and our arrows; therefore take him and bind him, and away with him.

Isn't it interesting that the unbelievers were willing to ascribe Samuel's miraculous protection to the power of the devil rather than believe it came from God. Apparently any ridiculous belief is better than the truth when the truth involves God. Today people would rather believe in the random chance of evolution than to admit an Intelligence in their own creation.

Alma 44:9

Behold, we are not of your faith; we do not believe that it is God that has delivered us into your hands; but we believe that it is your cunning that has preserved you from our swords. Behold, it is your breastplates and your shields that have preserved you.

Hear the words of Zerahemnah, which are echoed today by secular humanists. Miracles are seen through the eyes of faith. A miracle to a believer is a mere coincidence to an unbeliever. They both see the same thing, yet their spiritual inclinations alter their perceptions. To a disciple, God is a living power in their life. To an atheist, God is just an excuse for logical actions and reactions, with a little mix of random coincidences and happy accidents to explain the unexplainable. If you want to talk about faith, one has to be more gullible to believe in pure chance than to believe in a living, loving God. One may choose to live without God in the world, but that does not alter the reality of God's existence or his interest in our lives.

Alma 38:5

And now my son, Shiblon, I would that ye should remember, that as much as ye shall put your trust in God even so much ye shall be delivered out of your trials, and your troubles, and your afflictions, and ye shall be lifted up at the last day.

Blessings are predicated upon obedience. Trust in God is synonymous with faith in him. When we have faith in him, wonderful blessings will come into our lives. Of course, for us to recognize blessings, we must also have opposition. Shiblon is promised a full load of adversity, but the promised deliverance is greater than the trials from which he will be delivered. When we are faced with great trials, if we exercise faith, we can expect miraculous deliverance.

Alma 29:11

Yea, and I also remember the captivity of my fathers; for I surely do know that the Lord did deliver them out of bondage, and by this did establish his church; yea, the Lord God, the God of Abraham, the God of Isaac, and the God of Jacob, did deliver them out of bondage.

A pervasive theme of the Book of Mormon is remembering, especially remembering the captivity and deliverance of the House of Israel from Egyptian bondage. Their deliverance from slavery is a sign of God's power. It is also a reminder that just as God temporally redeemed his people, so he also has the power to spiritually redeem them. The miracles of the past help us believe in the miracles of the present. Redemption and rescue are always miraculous.

Alma 19:4

And she said unto him: The servants of my husband have made it known unto me that thou art a prophet of a holy God, and that thou hast power to do many mighty works in his name;

Wonderful works follow those who believe. The Lord has much work to do upon the earth among his children. He needs servants who will carry out his work. When we sign up to do his work, we can be assured that he will use us to the full extent possible. He does not have an abundance of faithful helpers. 

So what can we expect when we strive to become instruments in the Lord's hands? We can expect to do mighty miracles. Not to impress or to fill our vain ambition, but to serve God's children and bring them to Christ. If that is our aim and desire, God will find many ways to use us. Some may be publicly impressive, most will be quietly private, but all will be with power. 

Second Nephi 27:23

For behold, I am God; and I am a God of miracles; and I will show unto the world that I am the same yesterday, today, and forever; and I work not among the children of men save it be according to their faith.

If God does miracles, and if he doesn't change, why is he not doing miracles today? Because of this one additional fact: he works only by faith. He has always worked by faith and will always today and in the future work only by faith. If we don't see his miracles today, we shouldn't look at God's failure, we should look at our own. If he doesn't change, then we must have changed. When we turn to him, he turns to us.

Second Nephi 27:23

For behold, I am God; and I am a God of miracles; and I will show unto the world that I am the same yesterday, today, and forever; and I work not among the children of men save it be according to their faith.

It is important for us to understand that God does miraculous things, for the world is trying to rob God of his power, or rather trying to rob us of a belief in miracles. The secular world claims that everything is knowable and explainable as a natural phenomenon or a random chance, the certainty of which is guaranteed by an unfathomably large number of random opportunities and coincidences. God, on the other hand, claims he is in control, and nothing is random happenstance. I recent saw an unusual bridge arching over I-80 in Nevada. It was a beautifully constructed archway made of cement and decorative stone. It seemed to jut out of the side of a rugged hill and fall off steeply into a canyon on the other side of the freeway. No road led to it from the mountainside, and the angle into the canyon was far too steep to be negotiated by a vehicle. Despite the fact that I could not explain the purpose of the structure, it did not for an instant occur to me that it was randomly placed where it was. And it certainly did not cross my mind that a billion years of wind and water moving sand and rock particles might have formed such a well designed and executed structure. The evidence of intelligence in design was indisputable, however unintelligible the purpose behind the structure might have been. While that bridge might have been a boondoggle to use tax money, God does not do anything as a boondoggle. He has purpose, and everything he does has purpose, whether we understand it or not. For centuries men have tried to explain what God has done, and over and over they have had to change their theories as new knowledge has come to light. Mortal man will never fully understand God's power, and so God will always be a God of miracles.

Second Nephi 26:20

And the Gentiles are lifted up in the pride of their eyes, and have stumbled, because of the greatness of their stumbling block, that they have built up many churches; nevertheless, they put down the power and miracles of God, and preach up unto themselves their own wisdom and their own learning, that they may get gain and grind upon the face of the poor.

Nephi saw our day clearly. The Gentiles of whom he speaks are the European Christians and their descendants in the Americas. Nephi saw the Book of Mormon come forth among them when they are at the height of confusion and apostasy. He saw many churches, yet none acknowledge the power of God. They teach the philosophy of men, mingled with scripture, for they deny revelation. Nevertheless, God speaks today. He speaks to prophets and to individuals. He offers powerful miracles. He yearns for us to draw close to him so he can draw close to us.

First Nephi 17:51

And now, if the Lord has such great power, and has wrought so many miracles among the children of men, how is it that he cannot instruct me, that I should build a ship?

God is not stingy with his power.  He is willing to use it constantly in our behalf.  He has preformed miracles for others, and he will perform miracles for us. He is not partial or capricious.  Anyone who exercises faith, humbles himself, trusts in Christ, and seeks diligently can receive manifestations of God's power in his life. God works by power. Whenever we see his power in action, we call it a miracle. Miracles are acts that defy limited human reason, but they do not defy God's reason. He can empower us to do anything he wants done. His power can remove the constraints by which we normally operate in the world. If we are willing to accept it, and set aside our personal fears and doubts, God can do many wonderful things through us.
